PACKAGE FOR INCANDESCENT LAMPS Filed April 12, 1956 3 Sheets-Sheet 3 INVENTOR. JAMES A. MAHONEY United States Patent 2,869,720 PACKAGE FOR INCANDESCENT LAMPS James A. Mahoney, Marblehead, Mass.

Application April 12, 1956, Serial No. 577,758 1 Claim. c1. 206 -65) This invention relates to wrappers or cartonsfor shipping, stacking, displaying and vending fragile articles and more particularly to a form of carton especially adapted for the handling of incandescent lamps. A principal object of the invention is to produce an inexpensive carton of the character indicated which may be made of a single sheet of cardboard, corrugated or otherwise, properly scored, and which, when loaded with lamps and folded, will be sufficiently rigid to insure the necessary protection against breakage.

A further object of my invention is the provision of a novel wrapper for packing incandescent lamps, made from a rectangular blank of material whereby a minimum of material is used eliminating unnecessary waste.

The use of adhesives, staples or other extraneous fastening means is eliminated.

Another object of my invention is to provide such novel cartons which save substantial space on storage when stacked with one another.

Further objects of the invention will hereinafter appear from the following description of a preferred embodiment illustrative of the invention and shown in the accompanying drawings in which 7 Figure 1 is a plan view of the flat blank, cut-out and scored before folding into a carton;

Figure 2 is a perspective view of two cartons showing the method of loading and stacking;

Figure 3 is a front view of a loaded carton opened and folded for display purposes.

My wrapper carton consists of a rectangular blank scored by seven parallel transverse fold lines and terminating on one end in several wing tabs. These fold lines are so spaced and arranged that folds one, two, three and four are adapted to be in-folded, fold five, is an out-fold, while folds six and seven are likewise infolds, resulting, after folding, in eight rectangular panels. These foldings produce two protective compartments, one for the lamp bases and one for the lamp bulbs. These cartons are designed for economical space requirements for stacking and transportation and also are designed for effective storage and display purposes.

Referring to the drawings, the carton therein shown, as illustrative of one embodiment of my invention, comprises a rectangular cardboard blank 10 with one transverse end 11 being straight with the other transverse end 18A being provided with tabs 18 and 20 which may be straight or winged. The blank is provided with seven parallel transverse score lines 12, 13, 14, 15, 16, 17 and 18, dividing the blank into eight rectangular panels 32A, 32B, 32C, 32D, 32E,- 34, 35 and 33. Panel 32B is perforated with a multiplicity of apertures 37 of sufficient diameter to snugly receive the screw bases-of lamps 25, 26, 27 and 28 to be enclosed in the carton and also other apertures such as 38 to receive a fuse 31 or the like. Panel 34. may be provided with a cut out 29 adjacent to fold 16 and panel 33 may be provided with a registering cut out 30 adjacent to edge 18A. Panel encloses a hole 23 and panel 33 encloses a hole 24, said holes being centered on and adjacent to fold 18.

3 2,869,720 Patented J an. 20, 1959 ice In packaging, the blank 10 starting on end 11, is infolded on score lines 12, 13, 14 and 15. These folds readily produce five panels 32A, 32B, 32C, 32D and 32B, forming a hollow rectangular prismatic enclosure 32 for gripping and enclosing the base with the top panel 32B perforated with apertures 37 and 38. Into these snug apertures the bases of lamps 25, 26, 27 and 28 are inserted by screwing the bases into the apertures. A screw fuse 31 may also be screwed into aperture 38. Out-fold on score line 16 and in-folds on score lines 17 and 18 produce panels 34, 35, and 33 which form a hollow isosceles trapezoidal enclosure abutting the bulbs of said lamps. Insertion of tabs 19 and 20 into slots 21 and 22 automatically latches the carton into bulb protecting con dition without the use of adhesives or staples.

As illustrated in Figure 2, theassembled lamp cartons of this invention can be closely and compactly stacked by inversion of the base holding portion 32 of one lamp carton with respect to adjacent cartons, as for example cartons 36 and 36A. Substantial storage space savings is thus possible with the carton of this invention as compared with previously described cartons.

As illustrated in Figure 3, an assembled carton of lamps can, be used for display purposes in a store or for hanging storage in the home by detaching the tabs 19 and 20 from slots 21 and 22, folding panel 33 against panel 35, allowing holes 23 and 24 to register, and suspending the partially open carton on a hook or nail through the holes.-

While the preferred embodiment of my invention has been described in detail, it will be understood that I do not wish to be limited to the particular construction set forth, since various changes in the form, material, proportions, and arrangement of parts, and in the details of construction may be resorted to-without departing from the spirit and scope of the invention, or destroying any of the advantages contained in the same, heretofore described and defined in the appended claim.

I claim:

A package consisting of an assembly of incandescent lamps and a structure for surrounding the assembly of said lamps, said structure comprising a rectangular, foldable blank having seven parallel transverse fold lines positioned along said blank forming eight rectangular panels, said second, third, fourth, and fifth panels being of equal width, said sixth, seventh, and eighth panels being of equal width the second of said panels being perforated so as to make circular apertures of sufficient diameter and spaced to accommodate and fit snugly the screw bases of said lamps, the eighth panel being extended by wing tabs adapted to engage with transverse slots positioned on the second fold line, the fifth of said folds being an out-fold, all other folds being in-folds,

said first, second, third, fourth and fifth panels when infolded at right angles to each other forming a hollow rectangular prismatic enclosure for the base positions of said lamps said bases being screwed into said second panel, said first panel overlapping said fifth panel, said second, sixth, seventh and eighth panels when in-folded forming a hollow isosceles trapezoidal enclosure for the bulb portions of said lamps, and. tangential to the sides and tops of said bulbs, the insertion of said tabs in said slots making a complete lamp enclosure, said'bases and said bulbs being separately protected, the shorter parallel side of said trapezoidal enclosure being common with and equal in length to the top of said rectangular enclosure, said packages ,being adapted to be stacked in (References on following page) 0 r 3 I 4 Refe rnces Cited in the file of this Qatent 2 514395 Scurich July 4, 1950 UNITED STATES PATENTS 2,761,785 Steger P 1956 -.1"""f""' "I-..-L" ".?f"1 1,892,547; Addi et al.
